Brick shed humidity

Hello there I was wondering if anyone could help
Or share some feedback, i have a brick shed 8ft x 5ft and I’ve tried my best to keep the humidity levels down in it but it never stays comfortable I have fitted a upvc door to replace the wooden panel one, installed tube heaters and even insulated above where the joists run along but still very humid in there, it might be worth mentioning that behind the shed is like a brick planter where the previous owner probably used so I don’t know if water getting trapped in the soil is making the shed more humid also I’ve attached photos of the plant bed and another of one two little pipes at the bottom of the shed which where they maybe lead to is the plant bed maybe they are for drainage not sure just fed up because some of my tools are starting to rust


Any help would be gratefully appreciated


P.s I am no expert at construction or
Would even call myself anywhere near that so please be gentle

I would say the wooden door was better, since it will allow air in, where as a uPVC door will go towards sealing the shed.

If the planter soil is right against your shed wall then yes, water can get in that way, so either get rid of the planter, or dig it all out and line it to stop water going into your shed. The other thing you do not mention is ventilation, you need a good airflow, adding heaters will just heat the air, it will be a waste as the warm damp air can not get out. Add a ventilation brick or two, front and back, or add a vent tile.

Hello thank you for your reply “Someone-Else” very much appreciated yeah the planter with the soil in is right up against the shed so I was thinking I might have to dig that out, and yeah there is ventilation/ air brick at the same end as the planter but it has a plastic vent cover on the outside which could be restricting air flow,

So how would I go about lining the bed ?
Do you have any idea what them pipes are in the photos ?
And should I take off this plastic vent cover that’s over the air brick ?

Once again thanks for your help very much appreciated

The only person who can say for sure what the pipes are for is the person who put them there.

Dig out all the planter, put a plastic liner in round all 3 sides and put back what you dug out, DPM would be a good choice for the plastic.
Ideally there should be at least 2 vents, opposite each other, so as wind blows it can go in, and take out moisture the other end.
The bigger the air vent the better, but you don't want flies to get in, make sure the plastic cover is not full of crud. (Technical term that is)

Okay I’ve got some polyurethane sheeting I can use if that’s feasible and I’ll put another vent in thank you so much for feedback and all the best mate
